Abstract: An information processing apparatus, an information processing system, and an information processing method, each of which: stores in a memory a retained log which has not been transferred to an external device, among a plurality of logs generated in response to execution of a job; and stop operating the information processing apparatus and reactivate the information processing apparatus, based on a number of retained logs.

Abstract: A device includes circuitry. The circuitry receives a search request requesting searching for one or more setting items of the device, the search request being input by an authenticated user, the authenticated user being a user authenticated to use the device. The circuitry determines one or more particular setting items to be displayed on a display of the device from a search result obtained in response to the search request, based on authorization information of the authenticated user for the one or more setting items. The circuitry displays, on the display of the device, the particular one or more setting items determined to be displayed on the display of the device.

Abstract: An improved information processing apparatus, an authentication method and non-transitory recording medium are provided. The information processing apparatus authenticates a user based on first authentication information input by a user to generate an authentication result based on the first authentication information, receives an authentication request generated by first application software, authenticates the first application software based on second authentication information to generate an authentication result based on the second authentication information when the authentication request includes the second authentication information, acquires the authentication result of the user based on the first authentication information when the authentication request does not include the second authentication information, and executes processing based on one of the authentication result based on the first authentication information and the authentication result based on the second authentication information.

Abstract: A remote management system is configured so that a management system remote manages a device through an intermediary device. The management system includes a protocol specifying unit configured to specify a protocol to establish connection between the intermediary device and the device, a priority specifying unit configured to specify priority order of a plurality of the protocols, and a request generating unit configured to generate a request including the protocol and the priority order. The intermediary device includes a communication control unit configured to establish connection between the intermediary device and the device by using the protocols included in the request in descending order of the priority order.

Abstract: An information processing apparatus includes circuitry to transmit network identification information of a network to a communication terminal via short-range wireless communication and acquire, from the communication terminal via short-range wireless communication, address information indicating an address on the Internet accessible by the communication terminal based on the network identification information. The circuitry notifies a plurality of pieces of connection information of the communication terminal using the address information acquired from the communication terminal, the connection information to be used for establishing a connection between the information processing apparatus and the communication terminal through the network.

Abstract: An information processing apparatus is for arranging at least one dot, which expresses information relating to image data, in the image data. The information processing apparatus includes processing circuitry configured to create an edge image of the image data; determine a position near an edge in the edge image to be a position of the at least one dot; and arrange the at least one dot at the determined position in the image data.

Abstract: An information processing system includes an image processing apparatus and a server device, the image processing apparatus including: a read controller that reads a recording medium on which a first image is formed and in which identifying information of the first image is embedded and generates a second image; a detector that detects the embedded identifying information from the second image; and a first transmitter that transmits the detected identifying information and the second image to the server device, the server device including: a storage that stores an image and identifying information of the image in association with each other; a determining unit that determines whether the transmitted identifying information is stored in the storage unit; and a storage controller that, when it is determined that the transmitted identifying information is stored in the storage unit, stores the transmitted second image in association with the stored identifying information.
